Title: Print apparatus
Inventor: YAMAGUCHI YOSHIHIRO
IPC: B41J2/36
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To automatically adjust a print density by sharing members to be used for normally processing photoprint images without setting a special measuring device such as a densitometer or the like in a print apparatus of a TA system. SOLUTION: A test pattern of a predetermined photoprint gradation value (gray) is printed to a print paper 50 similarly to a normal image. Then, the test pattern of the print paper is supplied between a home position(HP) sensor 40 and a fixing lamp (fluorescent lamp 42 for Y fixing). Light irradiated from the lamp 42 and reflected by the test pattern is received by a light receiving sensor of the HP sensor 40. A density of the test pattern is detected from a quantity of the received light. A quantity of heat to be added to the print paper 50 by a thermal head 36 is adjusted to turn the density to a reference density. A variation in print density because of dispersion in characteristics of the print paper 50 or the like is prevented accordingly.

Title: Detector for remaining quantity of toner of developing device
Inventor: MORI TAKAHIRO
IPC: G03G15/08
Filed: 1977-11-28
Abstract: PURPOSE:To perform accurate detection of remaining quantity of toner by transmitting the turning of a cam cooperating with a toner replenishing roller to other cam by way of a torsional coil spring according to the quantity of the toner. CONSTITUTION:A shaft 6 and a replenishing roller 5 and detecting cam 9 are rotated 1 turn by means of a 1-turn clutch via gears 8, 10 and turning of a cam 9 is transmitted to a detection cam 11 by way of a torsional coil spring 12. The axis of this cam 11 is connected to the shaft 6 and detecting member 7 and receives resistance power according to the toner quantity during passing of the toner 3. As a result, the turning transmission angle from the cam 9 to the cam 11 changes according to the rate of flow-down of the toner 3. Hence, if a micro-switch, etc. are driven by way of the cam follower actauted by the cam 9, the detection of the specified remaining quantity of the toner is accurately accomplished according to not the height of the toner but the resistance of the time when the detecting member passes in the toner.

Abstract: PURPOSE:To effectively prevent the generation of rust on any sheared face of an explosion-proof band, by forming the belt-shape explosion-proof band in such a way as shearing a base material plate so that its rust preventive film is extended into about more than 1/3 of thickness of the base material plate so as to stick the extended part onto the sheared face. CONSTITUTION:Generally, a wide steel plate with thickness of 0.6 to 1.4mm is used for an explosion-proof band but the steel plate 12 with thickness of 0.8mm is used for this case. And both faces of this steel plate 12 are covered by aluminum or aluminum and zinc containing plating in thickness of 10 to 25mum serving as the rust preventive film 11, and the plate is used as a base material to form the explosion-proof band. And the base material plate is sheared in the width of the explosion-proof band, thus the explosion-proof band in which a plating, that is the rust preventive film 11, covers in the thickness direction of the steel plate 12, about more than 1/3 of its thickness can be obtained. Thus, generation of the rust on sheared face of the explosion-proof band can be effectively prevented and manufacturing cost of the band can be greatly reduced.

Title: Non-volatile semiconductor memory
Inventor: MARUYAMA TADASHI
IPC: G11C17/00
Filed: 1988-06-09
Abstract: PURPOSE:To improve an operation margin when data is read by providing a constant voltage output circuit between a raw decoder and a word line and causing a reading voltage, which is supplied to the gate of a memory cell, to be lower than a power source voltage. CONSTITUTION:The '1' level voltage of a decode signal, which is outputted from a raw decoder 10, is the power source voltage, for example, 5V. Such a signal voltage is lowered to be the voltage 5V or less by passing through a constant voltage circuit 50. Thus, when the data is read from each memory cell MC, the gate voltage of the cell MC can be set to an intermediate value between the threshold voltage of an electron injecting cell and the threshold voltage value of a threshold voltage in an electron non-injecting cell. Thus, the data holding time is prolonged and even when the threshold voltage of the electron injecting cell is lowered to the 5V, the correct data can be read from this electron injecting cell.

Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To embody a laser gyroscope which prevents the destruction of a semiconductor laser and is safe even if there is a rapid fluctuation of a power source or a large angular speed input. SOLUTION: A camera microcomputer 11 stops the output of a drive signal 11a and an excitation signal 11b when the angular speed is larger than a prescribed value. The camera microcomputer outputs the drive signal 11a and the excitation signal 11b again and detects the angular speed again upon lapse of the prescribed time (for example, one second) thereafter. If the angular speed exceeds the prescribed value at this time, the output of the drive signal 11a and the excitation signal 11b is stopped. The power source 117 a detects that the fluctuation in a high-frequency component is larger than the prescribed value by a comparator 117c. The signal is sent directly to the camera microcomputer 11. When the signal is inputted to the camera microcomputer 11, the camera microcomputer 11 stops the output of the drive signal 11a and the excitation signal 11b.  The camera microcomputer starts the output of the drive signal 11a and the excitation signal 11b with a delay of, for example, one second, from the time the fluctuation of the high frequency does not exist in the power source any more.
